Mr. Zhang is a retired teacher living with throat cancer, and a lonely supporter of late Chairman Mao. A “revolutionist” normally must have some friends or supporters, but sadly this is precisely what Mr. Zhang does not have. He keeps looking for friends in his family, “allies” and “promisingly innocent” young students but is always disappointed in the end, until he finds Cao Diao, the director of the film, a 20-year-old student who is willing to listen, and who cares to debate about Mao after all.  This film was shot between 2013 and 2014 in Ji’an/Mt. Jinggangshan region of Jiangxi province, known as the birthplace of Mao’s Revolution. This film is one of the China Dreams Series supervised by Jian Yi.
